Generally there are cool things going on in this game but for me it just barely misses the mark. If nothing else, there are lots of fun patterns and ideas presented throughout. I especially like the stuff going on in stage 4. The different shot types and game modes gives you a lot to play around with too.
It definitely seems more geared towards scoreplayers. As fun as a lot of the patterns are in theory, in practice many of them are unnecessarily visually busy, very fast, and very punishing without extensive routing. It's easy to start hemorrhaging lives if you don't have time to react, which is going to be more often than you think.
It seems like this is the dev's first game, which is honestly pretty impressive especially considering how ambitious it is. Still, I think they have room for improvement.
